To all 'whomit may concern: 4

Be it known that I, JOSEPH M. STELMACH, a citizen of the United States,residing at Kensal, in the county of Stutsman and State of North Dakota,have invented certain new and useful Improvements in Zero- SettingDevices, of which the following is a specification.

This invention relates to a gasolene gage and register and the principalobject of the invention is to provide a device of the characterdescribed which is so constructed that it will indicate the amount ofgasolene placed in a storage tank of an automobile the amount ofgasolene used during theand register the amount of gasolene used whileon a trip and also register the amount of gasolene used during a season.

Another object of the invention isto provide improved means foroperating the gage and register so that as the tank is filled withgasolene the hand indicating the amount of gasolene inthe tank will moveand so that when the automobile is running the register will operateand. indicate the amount of gasolene used and the gage finger will moveto show the amount of gasolene still remaining in the tank.

Another ob ect of the invention is to construct the register that thedial showing the amount of gasolene used on a trip may be turned backwithout the dial showing season being turnedback.

Another object of the invention is to 'So' construct the register thatwhen filling the tank with gasolene the indicating hand may be movedwithout the rest of the mechanism moving.

This invention is illustrated in the accompanying drawings, wherein-eFigure 1 is a side elevation showing the gasolene tank and pipe leadingtherefrom with the register and gage carried by the pipe; Fig. 2 is avertical sectional view through the gage and register; Fig. 3 is afragmentary view showing a part of the register operating mechanism;Fig. 4 is a vertical longitudinal sectional view through the gasolenetank; Fig. 5 is 'a ,view showing the face of the register and gage inelevation; Fig. 6 is a view showing the gears in Fig. 3 in elevation andshowing the'manner of slidably mountin'g'the axle of the'gears; and Fig.7 is a fragmentary view showing the pipe disclosed in .Fig. 1 inlongitudinal section.-

The gasolene tank 10 may be the tank of an automobile, motor boat or anyengine of the internal combustion type run by-gasolene or thelike. Thistank 10 is filled through the inlet 11 which is normally closed by thestopper 12. The tank is also provided with an opening 13 which is closedby a cover plate 14 through which there extends a neck 15 and from whichthere also extends the guiding arms 16. These guiding arms 16 extendthrough openingsformed in the float 17 to guide the vertical movement ofthe float and prevent longitudinal movement of the float in the tank. Aweight 18 is carried by the flo'atso that as the gasolene is used thefloat will move downwardly and thus draw upon the line, 19, the innerend of which is connected with the eye bolt 20 carried by the float. I

A tube 21 which is formed-of small ing leads from the neck 15 theregister and gage, the.sections of the tube being connected by elbows22, the central portions of V which are enlarged to form ulleyhousings.The line 19 passes throng the tube and around the pulley wheels .23.rotatably mounted in the housings of; the elbows 22 and is connectedwith a sprocket chain 24 leadin seen t at as the float moves downwardlyin the storage tank. 10 the sprocket chainwill bem'oved to operate thegage and regis ter and. that as the tank is filled with gaso= 'lene thespring will contract thus moving the sprocket chain to operate the gage.

The gage and register is provided with a housmg 26 to which there issecured a de pending casing 27.. This casing 27 is provided withpartitions forniing 'a s ring housing 28 in which spring 25 ispositioned with ts lower (end connected with the closure 29-01 thespring housing and also formmg aconduit 30 with whichthe tube 21 isconnected andthrough which the line 19 extends so thatit may beconnected with the sprocket chain 24 which extends into the upper endportion of the conduit 30. This" sprocket chain passes around a sprocketwheel 31 which carries a small gear meshmg with the teeth of gear 32 sothat as the sprocket chain moves the gear 32 will retate with its teeth33 acting upon the worm 34 to rotate vertical shaft 35. p

-A- frame 36 is mounted in the housing 26 and carries a shaft 37 uponwhich the: gear 38 and gage finger 39 are rigidly mounted;-

from 'a spring 25. It will thus be 3 l t. I The gear 38 meshes with theworm 40 carried by vertical shaft so that as the shaft 85 rotates thegage finger 39 will be oscillated and move to indicate the amount ofgasolene in the tank 10. A second gear 41 is carried by a shaft 42 andengages the opposite side of the worm so that as the shaft 35 rotatesthe shaft 42 will be rotated and rotary motion transmitted to the gearmounted upon a shaft 46 upon which gear 47 is rigidly mounted totransmit rotary motion to the shaft 48 through the medium of gear Shaft48 carries a suitahle dial 50 so that the amount of gasolene used duringthe trip may he readily ascertained hy looking at the face of the gageand register shown in Fig. 5. From an inspection of Fig. (3 it will hereadily seen that the shaft 48 is slidahly and. rotatably mounted in theslot 51 of the frame 36 and from an inspection of Fig. 25 it will hereadily seen that shaft 48 passes through a ring 52 with which spring 53is connected. This spring 53 is connected with the iinger 5lof key 55 sothat when. the key is turned to the dotted line position shown in Fig. 2the shaft 48 may he drawn upwardly and move gear 49 into engagement withgear 56 of key 56 thus permitting the dial 50 to he turned back withoutthe dial of the season register heing turned hack. The key 55 can thenhe returned to the normal position. The season dial 57 is carried hyshaft 58 upon which a gear 55) is mounted, the gear 5!) meshing with 'agear (it) which engages gear (51 so that rotary motion may he.transmitted to the season dial. Q

In the operation of this'device, the tank 10 is filled with gasolene andwill move the float l't'upwardly thus pern'iitting the spring 25 tocontract and rotate shaft 31. through the medium of sprocket chain 24thus causing the vertical shaft 35 to rotate and turn the gage hand 39to indicate the amount of gasolene placed in the tank. It has alreadyoeen explained that while the hand 39 is turning to indicate theamountof gasolene placed in the tank the pawlo tfi will hold gear 43stationary and as th teeth of the gear 43 are resilient gear 44 willpass gear 43 without turning the same. As the gasolene is used the float17 moves downwardly and will cause shaft 35 to be rotated in theopposite direction thus rotating the various gears and causing the tworegistering dials to move to indicate the amount of gasolene used duringa trip and increase the amount shown on the season dial. After returningfrom a trip the shaft 48 can be drawn to hring gear 49 into engagementwith gear 56 and key 56 then rotated to return the trip dial to show acipher. Shaft 48 is returned to its original position. It will thus heseen that while the trip dial is returned to show a cipher the seasondial will not he rotated and therefore the amount of gasolene registeredby the season dial will not he changed. A person ean'therefore keep arecord of how much gasolene is used on each trip and how much gasoleneis used in a season. He can also readily ascertain how much gasolene hasbeen placed in the storage tank hy noting the amount of gasoleneindicated hy hand 3!) hefore the tank is filled and then noting thepoint to which the hand 3) moved after the tank is filled.

\Vhat is claimed -is:

In a device of the character described a casing a setting elementincluding a gear in said casing, a shaft slidahly carried hy saidcasing, a dial carried by said shait, a gear carried hy said shaft,means for transmitting rotary motion to said slidahly mounted shaftthroug the medium of the gear carried therehy, a shifting key rotatahlyconnected with said casing and having its in ner end portion providedwith a finger, and means connecting said finger with said slidahlymounted shaft wherehy sliding movement may he imparted to said shaftthrough the rotation of said shifting key.

in testimony whereof I ailix my signature in presence of two witnesses.I
